What is the relationship between genes DNA and proteins

Answers

Answer:

Although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits. While your genetic makeup does indeed determine physical traits like eye color, hair color and so forth, your genes affect these traits indirectly by way of the proteins created via DNA.

Hopefully, this answer helped! :D

Answer:

Most genes contain the information require to make proteins. The type of RNA that contains the information needed to make protein is called a messenger RNA or mRNA and it carries the message from the DNA out of the nucleus into the cytoplasm

A growling stomach and the stimulation of hunger represent the

A
integumentary system and the endocrine system working together.
B
excretory system and the respiratory system working together.
с
digestive system and the nervous system working together.
D
muscular system and the skeletal system working together.

Answers

A growling stomach and the stimulation of hunger represent the digestive system and the nervous system working together. The correct option is c.

What is hunger?

Hunger is primarily a biologically induced desire for food, which is required for survival.

Hunger can thus be regarded as a quantifiable biological trait of humans that predicts the willingness to eat as well as the amount of food consumed.

During fasting, the stomach secretes the "hunger hormone" ghrelin to promote food intake.

Ghrelin stimulates appetite by activating its receptor GHSR1a in the brain's hunger sensing neurons, and thus represents a promising avenue for the development of anti-obesity treatments.

A growling stomach and the stimulation of hunger represent the digestive and nervous systems collaborating.

Thus, the correct option is C.

write a five sentence paragrgh explaining the cell cycle

Answers

Answer:

The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.

New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.

Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.

The two main parts of the cell cycle are mitosis and interphase.

Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”

The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.

Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.

Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.

In a car, how does an air bag minimize the force acting on a person during a collision? It increases the change in momentum of the person. It decreases the change in momentum of the person. It increases the time it takes for the person to stop. It decreases the time it takes for the person to stop.

Answers

Answer:

C

Explanation:

Just took the test and the answer is C, It increases the time it takes for the person to stop.

The air bag minimize the force acting on a person during a collision due to decreasing the time it takes for the person to stop.

How air bag minimize the effect of force during collision?

Air bags are used in vehicles because they are able to minimize the effect of the force during a collision. Air bags minimize the effect by extending the time required to stop the momentum of the driver and passenger.

So we can conclude that air bag minimize the force acting on a person during a collision due to decreasing the time it takes for the person to stop.

c. in humans, for every trait we can only have two alleles. but that trait can be controlled by many alleles. there are no limits on how many alleles can control a trait.
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
e. if humans were diploid we would only have one allele per trait
Helpppp pleaseee

Answers

Answer:

d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes

Explanation:

Being diploid means humans carry two sets of chromosomes. Since we have both dominant and recessive gene types, humans can mask the effect of recessive alleles since the dominant trait will be seen in the phenotype or genotype since it is a dominant gene. The effect of the recessive allele will show up only if both diploid genes are recessive.

The first phase is interphase, during which the nucleus divides and the DNA replicates. The second phase is mitosis, during which the cytoplasm divides. The third phase is cytokinesis, during which the cell divides into two daughter cells.

What is cell cycle ?

The cell cycle is the series of events that take place in a cell leading to its division and duplication. It consists of two major phases: interphase and the mitotic phase. The mitotic phase is further divided into two stages: mitosis and cytokinesis.

During interphase, the DNA of the cell is replicated in preparation for cell division. This phase is divided into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

During G1, the cell grows and prepares for DNA synthesis. During the S phase, the DNA is replicated, resulting in two identical sets of chromosomes. Finally, during G2, the cell prepares for mitosis.

After interphase, the cell enters the mitotic phase. During mitosis, the replicated chromosomes condense and line up at the center of the cell. The nucleus then divides into two identical nuclei, each with a complete set of chromosomes.

After mitosis, cytokinesis occurs, which is the process by which the cytoplasm divides, separating the two daughter cells. The cytoplasmic division usually occurs simultaneously with the telophase stage of mitosis, resulting in the formation of two genetically identical daughter cells.

Therefore, interphase is the phase in which DNA replicates, mitosis is the phase in which the nucleus divides, and cytokinesis is the phase in which the cytoplasm divides to form two genetically identical daughter cells.

1. The Biosphere is a life-supporting stratum of Earth's surface, extending from a few Km into the atmosphere all the way to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients

2. Humans burning fossil fuels and growing animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. Humans have caused threats to non-renewable resources, CO2 production& global warming, as well as over-competition for food between native and introduced species.
